I have a regular old monochromatic laser printer that uses a standard black
cartridge. I have a need to print on clear labels that will be affixed to a
black connector shell. Black on black ain't gonna cut it. I'd prefer
white, but a yellow or some other bright color will do just fine.

Anybody seen such a beast?

Of course, just use a color laser printer. They use CMYK AFAIK, so you
should be able to print just yellow.

Is all toner pretty much the same?

I'm wondering if you can just go buy a color cartridge and steal the
toner out of it.
Would probably be messy as hell though. But you could try patience
and steady hands.
Would probably need to blow out the black cartridge with high pressure
air or something.

Also, I think toner might be bad for your health (so don't breathe
it), and I wouldn't be suprised if it were flammable?

Another idea I just had:
Those little label makers work really well. Not all of them of
course, but some of the Brother models do quite a nice job. And not
too expensive.

If you don't want to go that route, you could use the same tapes that
they do, affix the tape to the connector shell, and then your decal to
the tape. So connector-tape-decal.
Comes in white. And of course, this won't work if you need a width
greater than about an inch or so. I think that could look rather
professional in low prototype quantities?

I would think that if you contacted one of the numerous toner
refillers
who are now able to do this unencumbered,

they could give you any combination of casing/contents you desired.

No - I had a few toner refill kits with large bottles for specified
printers, and a full spare toner cartage for another printer that I didn't
have. Mixing and matching toners works in some cases others it doesn't not
come off the drum properly, and leaves shadows, etc (makes it look like the
drum is bad), or even almost no print at all with some printers. Other times
it works great.

Not too bad - do it outside the first time. It's fairly dense. Have a small
funnel, maybe a larger one too (when I used to do this, I made a larger one
with a sheet of paper when needed)
But you could try patience
and steady hands.

I can't see it being good for your health. Another reson to do it outside.
and I wouldn't be suprised if it were flammable?

Most likely, but I never had a problem with it.

THis is production, and I don't think my customers would go for it.

What about a pad printer?
Depending on your volumes, you might even be able to do them by hand,
without all the fancy jigs typically involved - but I've never tried
it without the fixtures.

Are the connector shells smooth or pebble-finish, or ??
What kind of shells? (I'm thinking "DB25" here.)
Or more to the point, what will be the dimensions of your finished
text?

I know, just print yellow, which is what the OP stated as an
alternative.

I don't think that the toner ink is so thick and opaque to reflect the
light from above the paper.

You could do the opposite: print the black background on a white sheet, and
keep the text unprinted... a little expensive though :)

My wife has a Dymo Thermal Printer, which prints on white or
_transparent_ stick-on labels of a variety of sizes.

Perhaps print "negative" so that letters are clear, apply white paint
on the back-side before sticking down ?:)

Or, as it just struck me, apply the dab of white paint to the
connector shell.

Or print "negative" on yellow labels?

This label printer uses TZ tape which comes in 5 different widths and
many colour combinations including white on clear.

Yes, but they use subtractive syntesis, not additive.

True. The yellow pigment absorbs magenta and cyan light, and
reflects the yellow. It's going onto a black panel, so I
presume it's supposed to be reflective.

Cheers!

It absorbs magenta and cyan light, and *transmits* the yellow. The
paper does the reflecting.

At least very similar, all current versions are low melting temp
plastics with colorings in (sub) micron powders.

Very definitely. All PM10 and smaller powders are inhalation health
hazards.
, and I wouldn't be suprised if it were flammable?

And potentially an explosive, think flour-air explosions, it is
usually a flammable plastic.

Actually, you can get white on black for P-touch and similar. One
adhesive label and presto. Or with a stamp like apparatus and epoxy
ink.

Magenta light? You may be betting too much on the ink not being
opaque.

Really? What color is a "yellow" pigment, when
viewed in a transparent container?

To be sure, the characteristics of the paper contributes
to the final color, but to say that a "yellow" pigment
transmits yellow light while blocking other wavelengths
is a misleading.

Really? What color is a "yellow" pigment, when
viewed in a transparent container?

If it's translucent, the colour of the background (whatever's behind the
container) minus (most) blue. If it's opaque, the colour of the
illumination minus blue. If it's between, then some combination of the two.
To be sure, the characteristics of the paper contributes
to the final color, but to say that a "yellow" pigment
transmits yellow light while blocking other wavelengths
is a misleading.

In order to function as the "Y" in "CMYK", it needs to transmit yellow
light while substantially attenuating blue light[1]. It may also
happen to reflect some light, but that isn't necessary for it to function
as ink or toner. Too much reflection would make it unsuitable for
making transparencies.

For printing on white paper, reflection is equivalent to transmission;
for transparency, reflection is equivalent to absorbtion. If there's no
reflection, you get the same results for both paper and transparency,
which is a desirable property for general-purpose process-colour (CMYK)
inks.
